8-16Do-it-yourself

• If the battery is labeled “do not open” it ismaintenance free and battery fluid
should not be checked. It is recom-
mended that you visit a NISSAN dealer or
a qualified specialist workshop to con-
firm the battery’s performance.
• Keep the battery surface clean and dry. Clean the battery with a solution of bak-
ing soda and water.
• Make certain the terminal connections are clean and securely tightened.
• If the vehicle is not to be used for 30 days or longer, disconnect the negative (-) bat-
tery terminal cable to prevent discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
WARNING
• Do not expose the battery to flames,
an electrical spark or a cigarette. Hy-
drogen gas generated by the battery
is explosive. Explosive gases can
cause blindness or injury. Do not al-
low battery fluid to contact your skin,
eyes, fabrics or painted surfaces. Sul-
furic acid can cause blindness or in-
jury. Af ter touching a battery or bat-
tery cap, do not touch or rub your

engine running to avoid discharging
the vehicle battery.
NOTE:
If the battery is completely drained the
transmission will not manually shif t to
other positions.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.
The current sensor
OAis located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.
